REST API Enabler vs REST API – Head Tags

Like this plugin? Please consider leaving a 5-star review. By default, custom post types and custom fields are not accessible via the WordPress REST API. REST API Enabler allows you to: Enable the WP REST API for custom post types and specify WP REST API custom endpoints. Choose which custom fields to include in WP REST API responses for posts, pages, and custom post types. All enabled custom field data is included in the REST API response, nested under the rest_api_enabler key, like so: [ { "id": 179, "date": "2016-07-03T18:06:50", "title": { "rendered": "Test Job" }, . . . "rest_api_enabler": { "custom_meta_1": "Value 1", "custom_meta_2": "Value 2", "custom_meta_3": [ "Array value 1", "Array value 2" ] } } ] Note: prior to verion 1.1.0, all meta keys were included as top-level keys in the API response. Additionally, all values were returned as arrays, regardless of whether the original value was actually an array. This functionality is now deprecated as it risks key-name collisions. Please reference the rest_api_enabler top-level key instead. Usage Activate the plugin, then go to Settings → REST API Enabler in the admin. Click the Post Types tab to enable/disable post types and customize their endpoints. Click the Post Meta tab to enable/disable post meta (custom fields). NOTE: by default, the plugin does not display settings for protected post meta (post meta that begins with an underscore and is intended for internal use only). If you wish to include protected post meta in the plugin settings, you can use the rae_include_protected_meta filter to do so. The following code can be placed in your theme’s functions.php file, or in a custom plugin (on init priority 10 or earlier): add_filter( 'rae_include_protected_meta', '__return_true' );

This plugin adds all the tags in the head section of a website to WordPress REST API responses. It is perfect if you are using WordPress for a headless set-up and would like to add the meta tags generated by your WordPress SEO plugin (like Yoast SEO or All-in-One SEO Pack) to the WordPress REST API output. Requirements This package depends on the PHP DOM library. Most PHP environments have it by default so you don’t have to worry about that. In case you get some errors regarding this dependency make sure you have this library installed (you can take a look at this thread in the code repository). Compatibility This plugin is compatible and works out of the box with some of the most popular WordPress SEO plugins. These are the ones that we tested: Yoast SEO – (up to 13.5) All in One SEO Pack – (up to 3.4.2) WP SEO – Are you using a different SEO plugin and want to know if it’s compatible? Feel free to ask in our community forum. If you tested any other plugin, please let us know as well so we can update the list. How to use this plugin Entities with head tags The plugin has been developed to include the head_tags field to the REST API response of most of the WordPress core entities: Posts, pages, attachments and custom post types. Post types: for archive pages. Categories, tags and custom taxonomies. Authors. In a Frontity project If you are using Frontity, you just have to install the @frontity/head-tags package and it will work automatically. In a different project You need to understand better how it works and add the data manually. How to fetch the head_tags field manually You have to get each entity from its respective REST API endpoint. For example: for fetching the posts, you should go to /wp-json/wp/v2/posts&id=123 endpoint; for fetching the categories, you have to go to wp-json/wp/v2/categories&id=123, and for custom post types or custom taxonomies, it would be a different url in each case. In the case of the homepage, it’s less intuitive and you should go to /wp-json/wp/v2/types/post. As previously said, each entity has a different endpoint so if you aren’t familiar with this, you should check out the WordPress REST API reference for more information. Inside each endpoint, it will be a new field named head_tags, which will be an array of objects representing the tags that WordPress would normally include inside the html head element. These objects have the properties tag, attributes and content. For example for these HTML tags: Hello wordl! - My Site " /> This would be the content of the head_tags field: "head_tags": [ { "tag": "title", "content": "Hello world! - My Site" }, { "tag": "meta", "attributes": { "name": "robots", "content": "max-snippet:-1, max-image-preview:large, max-video-preview:-1" } }, { "tag": "link", "attributes": { "rel": "canonical", "href": " " } } ] Settings The settings of this plugin are really simple. Purge cache In order to not affect the performance of your site, the head_tags field is cached for all your responses. Each time you update a post/page/cpt or a taxonomy, the cache for that entity will be purged automatically. In case you make global changes (i.e. your permalinks or your global Yoast settings) use the Purge button to clean the whole cache. Enable output By default, the head_tags field is included in the common endpoint of each entity. You can configure it so it doesn’t appear by default and to be shown when you include the head_tags=true query. For example, with the output disabled, https://test.frontity.org/wp-json/wp/v2/posts won’t show the head_tags field unless you have the query ?head_tags=true at the end. Skip cache In case you want to skip the cache, you can do so by adding to the query the parameter skip_cache. There are some cache plugins for the REST API which also use the same parameter. In case you want to ignore the cache for the REST API call but not for the head tags, you can use skip_cache&head_tags_skip_cache=false.
